[mythtv-users] Change filesystem format in place?

[Richard Shaw]

I currently have a 2TB drive formatted EXT4 and I'm considering moving to
XFS but I don't have a spare 2TB drive to move the recordings to.

Does anyone have a practical method of doing this in place?

I'm thinking:

1. expire just enough old recordings to create a decent amount of space
2. shrink the ext4 partition as much as possible
3. create an xfs partition
4. move as many recordings that fit to the xfs partition
5. Repeat steps 2-4 until I can remove the ext4 partition and use the whole
drive for xfs.

Risky?

Thanks,
Richard
